"postconf -d | grep mydomain" shows that the only such parameter
is mydestination:
mydestination = $myhostname, localhost.$mydomain, localhost
In any case, that's not really the right question, since mydomain
is used to fully qualify hostnames that have no dots (as with
localhost above), choose the right domain to append to hosts you
control should any of their names appear in mail headers or
envelopes in an unqualified short form.
